As someone who has suffered from parasites for years, and gotten rid of them permanently, I have a rarely echoed message to give;
There are plenty of great TEMPORARY strategies to get rid of intestinal parasites and parasites in other parts of the body: liver flushes, Miracle-Mineral-Supplement , colonics, garlic, Iodine and other supplements, and a whole lot more. Ive tried dozens of these 'cures', and most of them were effective... but they didn't fix the root cause, they were band-aids, but the parasites kept coming back.
The reason parasites keep coming back is because our bodies our in a state of stress, they are in a sympathetic dominant state. Certain micronutrient deficiencies, toxicity, and liverstones can also be a factor, but they are rarely the biggest cause. And they are all worsened by being in a sympathetic dominant state.
And what stressors put the body in this emergency state? All the things we think are healthy for us!
